863639-93-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 863639-93-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,3,6,3 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 863639-93:
(8*8)+(7*6)+(6*3)+(5*6)+(4*3)+(3*9)+(2*9)+(1*3)=214
214 % 10 = 4
So 863639-93-4 is a valid CAS Registry Number.
